A vehicle control system includes a transmitting electronic control unit for transmitting multiplexed protocol data units. The transmitting electronic control unit is enabled to transmit first and second protocol data units with corresponding first and second selector field values. A receiving electronic control unit is in electronic communication with the transmitting electronic control unit. The receiving electronic control unit is enabled to be programmed to operate in a first mode of operation or in a second mode of operation. The receiving electronic control unit is enabled to receive and process the first protocol data unit based on receipt of the first selector field value when operating in the first mode of operation and is enabled to receive and process the second protocol data unit based on receipt of the second selector field value when operating in the second mode of operation.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The method of claim 2, wherein the desired identity for the receiving electronic control unit is determined by an identity decider module.
4. The method of claim 2, wherein configuring the receiving electronic control unit post build includes flashing.
5. The method of claim 1, wherein mapping the first protocol data unit and corresponding first selector field value and the second protocol data unit and corresponding second selector field value to one or more frames for transmission uses dynamic multi-PDU to frame mapping.
6. The method of claim 1, wherein the first and the second selector field values represent different variants of a vehicle.
7. The method of claim 1, wherein the first and the second selector field values represent different model years of a vehicle.
8. The method of claim 1, wherein mapping the first protocol data unit and corresponding first selector field value and the second protocol data unit and corresponding second selector field value to one or more frames for transmission includes I-PDU multiplexer packing or container PDU packing.
9. The method of claim 1, wherein the first and the second selector field values are each predetermined.
10. The method of claim 1, wherein the first and the second protocol data units are each a dynamic segment with varying length or position.
11. The method of claim 1, wherein the receiving electronic control unit is not able to process the second protocol data unit when configured as the first version and is not able to process the first protocol data unit when configured as the second version.
15. The vehicle control system of claim 13, wherein the transmitting electronic control unit is connected to the receiving electronic control unit via a bus system that uses Ethernet technology or a controller area network with flexible data rate.
16. The vehicle control system of claim 13, wherein the first and the second selector field values represent different variants of a vehicle.
17. The vehicle control system of claim 13, wherein the first and the second selector field values represent different model years of a vehicle.
18. The vehicle control system of claim 13, wherein the first and the second selector field values are each predetermined and static.
19. The vehicle control system of claim 13, wherein the first and the second protocol data units are each a dynamic segment with varying length or position.
20. The vehicle control system of claim 1, wherein the receiving electronic control unit is not able to process the second protocol data unit when operating in the first mode of operation and is not able to process the first protocol data unit when operating in the second mode of operation.
